This project is a simple page to request random words from a popular Diceware words list. It uses a cryptographically sound method, but please use physical entropy for your highest security applications.

Selection of words happens in the browser. If you run this locally, no Internet access is required.

https://github.com/indexzero/http-server is an easy choice, but any web server will do.

git clone https://github.com/robert-claypool/almost-rw.git
cd almost-rw
npm install --global http-server
http-server # defaults to port 8080, http://localhost:8080/index.html

npm install # Install packages
npm install --global grunt-cli # Grunt CLI must be globally installed
grunt
